I've been reading about HL2 mapping for a month or so and I got the SDK a week ago. I've been playing with ladders, just to get a feel for them, and when I create one "by the book", it works. Not well, but it works. When I climb the ladder, it is a choppy ride up and down... kinda like an medium env_shake is happening.
I have a func_useableladder (not touching a damn thing) stretched out TALL. I have four standard prop_static ladder models stacked upon each other and the standard "half radial" dismount handrails at the top. I have 3 info_ladderdismounts at the top and 3 at the bottom. Since you can't resize the prop_statics, the model at the bottom of the stack is stuck in the ground quite a bit.
Anyone have any ideas?
